CARL BERG, 0F BROOKLYN, NEW YORK, ASSIGNOR, BY MESNE ASSIGNMENTS, TO THE BERG & BEARD MANUFACTURING 00. IN 0., A CORPORATION OF NEW YORK.

NON-REFIIQLABLE BOTTLE.

Application filed January 24, 1914.

To all whom it may concern:

Be it known that I, CARL BERG, a citizen of the United States, residing at Brooklyn, in the county of Kings and State of New York, have invented new and useful Improvements in Non-Refillable Bottles, of which the following is a specification.

The general object of this invention is to refine the construction of non-refillable bottles in point of effecting a simplicity of parts and in cheapness of manufacture.

And to these ends the invention consists of a valve adapted to benormally seated in a bottle neck and a closure for the mouth of the bottle, whereby the valve may be retained within the neck.

Other objects will appear and be better understood from that embodiment of my invention of which the following is a specification, reference being had to the accompanying drawings forming part hereof, in which:

Figure 1 is a vertical sectional view of the neck of my improved bottle.

Fig. 2 is a View similar to Fig. 1 but tilted so as to permit the escape of the contents.

Fig. 3 is a detail vertical sectional view of the valve.

The bottle 5 may be formed of any suitable material such as glass, porcelain, earthenware or the like, and is provided in the interior of the neck-portion thereof, with an annular shoulder 6, which serves as a valveseat for the valve 7 The interior of the bottle-neck, adjacent to the mouth thereof is screw-threaded, and is adapted to receive a closure 8, which cooperates with the valveseat in providing a valve-chamber 9.

The valve 7 which is located within the valve chamber, is preferably formed of metal and is tubular in structure; the upper end of the valve is flared outwardly and is provided with the serrations 10, as shown. A disk 11 is carried by the valve at the lower end thereof, and is secured thereto by means of crimping the lower edges of the tubular portion over and against the periphery of the disk as shown. Secured to the lower end of the valve by any suitable means, is a hemispherical portion 12, which may be formed of any suitable material, such as cork, rubber or the like, and is provided for the purpose of effecting the automatic positioning of the valve uponthe Specification of Letters Patent.

valve-seat, when the bottle is placed in its normal position, as shown in Fig. 1.

The closure 8 may be formed of any suitable material such as porcelain, or the like, and being provided with screw threads is adapted to be directed into the mouth of the bottleneck and to be secured therein by means of an adhesive, such as cement or the like. The closure is provided with a flange-like head 13, which diametrically corresponds to the exterior of the bottle neck, and is adapted to contact with the shoulder 11 of the neck, as shown. Centrally located at the under side 15 of the closure, is a depending portion 16, the end of which is rounded and is provided .with radial perforations 17. A vertically disposed cavity 18 is centrally located in the closure, and communicates with the perforations 17 the interior of the cavity adjacent to the mouth thereof is screw-threaded as shown at 19, and is adapted to receive a stopper 20, which is provided with a suitable thumb or head portion 21, for the purpose of removing and replacing the stopper when desired.

In order to secure the valve in a fixed position on the valve seat as shown in Fig.'

1, a rod 22, is carried by the stopper 20 and being directed into the cavity 18 is adapted to extend through the centrally located perforation 17 and bear against the plate 11 in the valve. In order to facilitate the centering of this rod on the plate, the latter is provided with a depression or pocket 28, for the reception of the end of the rod; thus it will be seen, that upon directing the stopper 20 into the cavity or recess 18, the rod will tend to bear the valve against the valve seat 6, and the inherent resilient qualities of the cork end 12 will effect a tight fitting of the valve, and prevent the leakage of the con tents of the bottle.

When it is desired to pour out the contents, the stopper is withdrawn from the closure, thus releasing the valve; the bottle is then tilted and the valve is displaced from the valve-seat by the weight of the liquid bearing thereagainst and the serrated end of the valve will tend to contact with the under surface 15 of the closure as shown in Fig. 2. The liquid will then pass through the valve seat into the valve chamber 9, and passing between the serrations 10, will flow through the perforations 17 into the cavity or recess 18 whence it may be poured into a glass or like receptacle.

What is claimed as new is:

The combination with a bottle having a valve seat in the neck thereof, of a valve on said seat and having a tubular upper end, a bored plug adapted to close the mouth of the neck and provided with a reduced depending extension projecting into the tubular upper end of the valve, said extension having a lateral port and a vertical port communicating with the bore of the plug, and a combined stopper and valve holding member extending through the bore of the plug and projecting through the said 15 vertical port into abutment with the valve to hold the latter on its seat.

In testimony whereof I affix my signature in presence of two witnesses.

CARL BERG.
